1. In the pseudocode used in this course, the symbol ← means:

2. What is the output of this pseudocode? sum ← 0; FOR i FROM 1 TO 3; sum ← sum + i; END FOR; OUTPUT sum

3. IF ... THEN ... ELSE ... ENDIF is an example of:

4. A pass should be given for a mark of 50 or above. The algorithm says IF mark > 50 THEN OUTPUT "Pass" ELSE OUTPUT "Fail" ENDIF, and mark is 50. What is true?

5. FOR i FROM 1 TO 4 means i takes the values:

6. What is the output of this pseudocode? n ← 1; WHILE n < 8; n ← n * 2; END WHILE; OUTPUT n

7. A program runs and prints the wrong total because the loop adds one extra time. This is a:

8. Which is a syntax error?

9. Valid marks are from 0 to 100 inclusive. Which pair is boundary test data?

10. Which input is abnormal test data for a numeric mark?
